Then a Stilt Legged Fly—I think genus Metopochetus. I found in the local sub-tropical rainforest. It appeared to be going around on a fallen log depositing eggs in small holes and crevices it found.

Lastly one of my favourite rainforest ants, the Red Spider Ant, Leptomyrmex rufipes [JAC: one site says that they cock their abdomens up in the air when disturbed, and this one seems to be doing that]:

Most excellent! It is always a trip to see how species are similar & yet different on opposite sides of the globe. That sand wasp could have been on a prairie in Iowa, as far as I can tell. That too is a good picture of a challenging insect, btw. They hover, but move suddenly. Land at their hole & vanish into it.

They’re a pain for me as I have developed some sort of arthritis over the last year and can’t get down on the ground to photograph these guys, I have to stand back a it and use a small telephoto lens. On the habits the ones around here spend a lot of time clearing the entrance to their burrows so they’re not as challenging to shoot as it sounds like your versions are.

It’s the tonneau cover on the back of my ute. The large weevils here have a habit of just letting go of branches and dropping to the ground at the slightest disturbance so I popped him up on the back of the car for a better shot then put him back in the bush where I found him.

some of the weevils are super frustrating, they curl up into an unphotogenic ball and stay that way for about as long as you’re willing to wait. At least these guys spread out their legs again when you let them rest somewhere.
